Beryllium Processing | Equipment, Flow, Cases

Mozambique and a few other countries mine small amounts of beryl. The United States produces and exports large amounts of beryllium alloys and compounds, and thus is a net importer of ores, but a net exporter of finished beryllium products. Small amounts of beryllium become available from the recycling of beryllium-containing scrap.

SELECTION OF MECHANICAL FLOTATION EQUIPMENT

Mechanical flotation cells can be broken down into two broad categories based on how air is introduced to the cell. In a self aspirated flotation cell air is introduced to the slurry, the vacuum created by the rotorusing . In a forced air flotation cell air is generated external to the cell by a low pressure blower,, and pumped down the

Separation of aluminium from beryllium in aqueous …

A fluoro-complex of aluminium is selectively precipitated by sodium ion from a dilute aqueous solution aluminium, beryllium, fluoride and potassium ions at a pH near 3. Subsequent flotation of this precipitate with long-chain alkylamines is affected by carbon chain length, pH, concentration of fluoride ion, rate of gas flow into the flotation cell and micellar form of the collector.

Beryllium Extraction and Beneficiation

Beryllium Extraction Process Flowsheet. Flotation offers the best means for recovering beryl in concentrate form. Much of the flotation technique developed in separation of feldspar from quartz and mica is applicable. In general, beryl will concentrate with the feldspar flotation product.

This paper presents some aspects of the fundamentals of beryl flotation with sodium dodecyl sulphate (SDS) and sodium petroleum sulphonate (SPS) collectors, as well as the influence of the presence of metallic cations and superficial leaching of the mineral with cold HCl and with HCl and HF on the floatability.

INVESTIGATIONS ON FLOTATING BERYLLIUM (Journal …

Beryllium activation and fluorspar activation with multivalent metal salts, contained in natural water and waste products of mills, increase the flotation extraction of minerals when using oleic acid as a collector. lt is shown that the use of Na-cationized water for the flotation of synthetic mixtures of beryllium-albite and beryllium ores ...

GB952246A

The underfloat from cell 13 has water, DERV fuel oil and more oleic acid added in a tank 16 and is passed to a flotation cell 17. Concentrate floated from cells 13 and 17 are passed to a cell 19 which is used as a washer and thence to a thickener 23. Tailings from cell 17 pass to waste line 2 and water from the thickener to tank 25.

Separation of aluminium from beryllium in aqueous …

Subsequent flotation of this precipitate with long-chain alkylamines is affected by carbon chain length, pH, concentration of fluoride ion, rate of gas flow into the flotation cell and micellar form of the collector. Temperature has little effect on recovery.
